Hi, I'm Sasha.

Engineer who never stopped typing.

I run two companies, write code most days, and recently discovered that one experienced engineer with the right AI setup can ship like a team of ten. I'm having more fun building software in 2026 than I did in 1998.

The Short Version

Chapter 1

I was supposed to be a mechanical engineer.

Five years at MIPT in Moscow studying applied mechanics and the theory of elasticity. Then a PhD at NC State on digital modeling of composite materials — never finished, because somewhere between simulating textile composites and writing my first compiler, the compiler won.

Chapter 2

Founded Tizbi in 1998 to keep writing code.

Bootstrapped a software firm with my co-founder Jim. 28 years later it's a global team. Funny thing — I never stopped writing code myself. Best way I know to lead engineers is to ship alongside them.

Chapter 3

Then 2025 happened.

Claude Code landed. I built an operating layer around it — memory, skills, prompts, agents. Now I ship at a pace that used to need a whole team. The fun isn't slowing. If anything, I'm building more confidently than at any point in 30 years.

What I'm Building

HumanData — RAG over 18,000+ customer calls at FlameOFF Coatings. Whisper transcribes, Claude understands, dashboard surfaces what 18,000 calls would otherwise hide.
Tizbi Customer Portal — .NET 10 multi-tenant ops hub. 10+ sub-applications, one login, database-driven access control.
SEO-Kombain — 39-table analytics pipeline pulling from 5 different sources every night. Solo build, end to end.
TradeAssistant — Algorithmic ETH/USD trading on Kraken. RSI divergence detector, autonomous position management. Mostly an excuse to write satisfying VB.NET.
BOAR SiteWork AI — Patent-pending construction estimation platform (USPTO 18/982,936). I architect, the team executes.
AI Operating Layer — the meta-project. Persistent memory, 150+ domain skills, MCP integrations, multi-tenant prompt architecture. The reason all the above ship fast.

Writing & Publications

Earlier in my career I contributed to research on composite materials — computational modeling work from the NC State textiles PhD era. More recently I've been collaborating on a white paper on AI-native software development using the operating layer I built. Both are getting added here; this section is intentionally a little empty for now.

The fastest path is email.

I read everything that comes in. No filters, no assistants — just me.
